Definitions
- the invention relates to a reduction gear with a driven worm shaft carrying two worms, with worm gears engaging in the two worms, with spur gears arranged on their shafts and with a. in this engaging spur gear arranged on an 'output shaft.
- the object of the invention is to simplify the construction of a reduction gear and to provide measures ' by which a play in the gear can be eliminated. This is particularly important if the gearbox is intended to drive machine parts, the movement of which must be carried out with the greatest accuracy. This is the case, for example, with industrial robots, such as those used for automatic welding.
- the object is achieved in that the two worm gears are arranged on the same side of the worm shaft and in alignment with one another, the two worms having the same and same pitch and the one of the two worms being under spring load to compensate for a gear play. It is particularly advantageous if one of the two screws is loaded by a plate spring, possibly a set of plate springs.
- the alignment of the two snails in alignment Wheels on the same side of the worm shaft simplify the construction of the reduction gear, the manufacture of the worm shaft being facilitated insofar as the two worms have the same pitch in the same direction.
- the two screws In the case of the gearbox described in the introduction according to FR-PS 2 455 221, the two screws must have an opposite pitch.
- the spring load of one of the two screws which is provided according to the invention, finally reliably compensates for play in the transmission and is structurally simple to implement.
- a worm shaft 2 is mounted in a housing 1, on which two worms 3 and 3 'are arranged, which have the same pitch in the same direction.
- the worm shaft 2 is driven via a bevel gear 4 in the illustrated embodiment.
- a worm wheel 5 engages in each of the two worms 3 and 3 'and the two worm wheels 5 are rotated in the same direction.
- the worm wheels 5 sit on shafts 6, which also carry gears 7. These gears 7 mesh with a gear 8, which is attached to an output shaft 9.
- one worm 3 'of the two worms 3 can be displaced on the shaft 2 in the axial direction and is under spring load, in the exemplary embodiment shown, by a plate spring 10.
